Definitions

  • the present invention relates to display devices or systems, in particular for displaying advertising.
  • a display device which has, generally speaking, a vertical axis of symmetry, comprising a fixed support consisting of two horizontal frames of hexagonal profile, which are mounted one above the other in a mutually confronting manner, and six display panels, which are distributed over the periphery of the support, and are each arranged vertically in a rectangular opening formed by two superposed sides of the support and in parallel with the axis of symmetry.
  • Each panel is mounted in first-side/second-side rotation on the support, about an individual axis of rotation, parallel with the axis of symmetry, and arranged along a vertical side of the rectangular opening closed off by said panel.
  • a rotary lower platform comprising six guide channels, each interacting with a stud provided below the lower side of each panel, makes it possible to drive said panels in rotation about their individual and respective axes of rotation while synchronizing their respective rotations so as to cause them to pivot at the same time in the same first-side/second-side or second-side/first-side direction.
  • each panel is effected inside the support and by sweeping over a cylindrical surface area whose radius is equal to the complete width of said panel. Consequently, the cylindrical volume circumscribing the support of hexagonal horizontal section must have a diameter of at least twice the width of a panel.
  • the subject of the present invention is thus a solution and, more precisely, a particular arrangement of the panels with respect to their support, making it possible to limit to a large extent the size in terms of volume and, in particular, according to its horizontal section, of a display device, and to do so on the basis of a given size of the display panels, especially of a given width of the latter.
  • each display panel is offset with respect to the median point according to the width of said panel, in such a manner as to form in the latter a relatively narrow section and a relatively wide section which are arranged on either side of said individual axis of rotation,
  • the gap separating the axis of the support and each individual axis of rotation of a panel is adjusted so as to permit solely the passage in rotation of the narrow section of the display panels, in the direction of rotation providing the first-side/second-side or second-side/first-side inversion of a given panel.
  • the solution according to the invention makes it possible to limit the working volume of the display device in proportion to the narrow section selected or adopted for each panel, on the basis of the distance separating the axis of symmetry of the support with respect to the median point or axis of symmetry of each said panel.
  • the support had an overall radius of 3 m 34.
  • the support has an overall radius of 2 m 71.
  • the solution according to the present invention appears to be particularly well suited to the case where the support equipped with the various rotary panels is mounted in a revolving manner, that is to say in rotation, about the axis of symmetry of said support with respect to a fixed stand or mount, since in this case it is precisely the cylindrical volume circumscribing the support which determines the size of the display device.
  • the solution according to the invention is even more suited to the case where the revolving support is mounted at the top of a mast, and about the axis of the latter, because in this case the first-side/second-side or second-side/first-side individual rotation of the panels can be carried out freely in respect of the external clearance of the wide section of said panels.
  • Width and “height” of the panels are understood as meaning the dimension of said panel orthogonal to the axis of symmetry of the support and the dimension of said panel parallel with said axis respectively.
  • FIG. 1 shows an overall perspective view of a display device in accordance with the present invention
  • FIG. 2 is a diagrammatic representation in plan view of the display device according to FIG. 1, with the various display panels in the first-side position,
  • FIG. 3 is also a diagrammatic representation in plan view of the display device according to FIG. 1, with the various display panels in the second-side position,
  • FIG. 4 shows in vertical section the means for driving a display panel in rotation, it being understood that the other two panels of the device according to FIG. 1 are driven in rotation in the same manner,
  • FIG. 5 is a diagrammatic representation in vertical section of the device for coupling two consecutive display panels, both in their first-side position and in their second-side position,
  • FIG. 6 shows in vertical section the upper plate of the revolving support belonging to the device according to FIG. 1, mounted in rotation on the upper end of the stand of the same device,
  • FIG. 7 is a diagrammatic representation in vertical section, still in the region of the upper plate of the revolving support according to FIG. 1, of the means of blocking said supports in rotation relative to the stand or mast,
  • FIG. 8 is a flow chart describing the control or monitoring program for the various functions of the present invention.
  • a display device comprises principally:
  • this stand comprising two sections, a lower one 1a of relatively large diameter and an upper one 1b of smaller diameter, serving as a swivel,
  • a revolving support 2 mounted in rotation on the upper part 1b of the stand 1, about the axis of the latter, this support comprising two plates 14 and 15 extending radially, an upper one 15 and a lower one 14,
  • each panel 4, 5 or 6 is mounted in rotation on the support 2, between the two plates 14 and 15 which are arranged heightwise on either side of said panel,
  • each display panel for example the panel 4, it revolves about an individual axis of rotation parallel with the axis 3 of the stand 1 and represented in concrete terms by the axis of the tubular support 57, described hereinafter in respect of the frictional security mechanism shown in FIG. 4.
  • the individual axis of rotation of the panel 4 is offset with respect to the median point A according to the width of the same panel in such a manner as to form in the latter a relatively narrow section 4a and a relatively wide section 4b, which are arranged on either side of the individual axis of rotation of said panel. As is shown in FIG.
  • the gap separating the axis 3 of the stand 1 and each individual axis of rotation of a display panel, for example that of the panel 4 is adjusted so as to permit solely the passage in rotation of the narrow section, for example, 4a, of the same panel, either in the direction of rotation 11, that is to say from the first-side position towards the second-side position, or in the direction of rotation 12, that is to say from the second-side position towards the first-side position, which two directions have been shown in FIGS. 2 and 3 respectively.
  • the synchronizing means 13 described hereinafter are used in combination with the various means 10 for driving in rotation, assigned to the various display panels 4, 5 and 6 respectively, so as to drive the latter in rotation, at the same time and in succession, in the direction of rotation 11 towards the first-side position, and in the direction of rotation 12 towards the second-side position according to FIGS. 1 and 2 respectively.
  • each display panel takes place, in the case of its relatively wide section, for example 4b, outside the imaginary space delimited the rotation of the revolving support 2, and, in the case of its relatively narrow section, for example 4a, inside this same imaginary space.
  • Such a rotation can be carried out without disadvantage, since the revolving support is situated at the top of the stand or mast 1, that is to say out of range of any human presence.
  • the overall size of the display device remains relatively limited, as is determined essentially by the distance separating the axis 3 of the mast and the individual axis of rotation of each display panel.
  • each plate 14 or 15 comprises 3 radial arms 18, 19 and 20, which are arranged at 120° relative to one another and mounted or fixed on a hub 16 or 17, which is mounted in rotation on the upper part 1b of the stand 1.
  • each individual axis of rotation of a display panel 4, 5 or 6 is arranged between the two ends of two mutually opposite radial arms in such a manner that each individual axis of rotation of a given panel is connected to the two hubs 16 and 17 via three arms 18, 19 or 20.
  • the means for driving various display panels 4, 5 and 6 in rotation comprise as many individual means 10 as panels.
  • Each individual means 10 is fixed at the free end of a radial arm, 19 for example, and consists in the coupling of a motor 61, a geared unit 62, and a vertical output shaft 63, arranged in parallel with the axis 3 of the stand 1, or along the axis of rotation of the display panel, for example 4, by means of a frictional security mechanism 22, making it possible to uncouple the motor 61 with respect to the same panel, and to do so under the control of the synchronizing means 13 described hereinafter.
  • the security mechanism 22 comprises a driving disk 23, which is fixed in rotation on the shaft 63 and arranged flat on the web of the radial arm, for example 19, by means of needle stops 64, and also a driven disk 24, which rests flat on the driving disk 23 by means of a frictional brass retaining ring 65.
  • this driven disk 24 which has a tubular part 24a which determines the axis of rotation of the display panel, and also a flange 24b parallel with the part 24c resting on the driving disk 23 and on which flange the display panel is mounted in rotation in an adjustable manner.
  • the means for synchronizing the rotation of the various driven disks 24 is achieved, at each individual means 10 for driving in rotation, by a pinion 66, which is fixed in rotation on the tubular part 24a and meshes with an endless chain 21, also shown in FIGS. 2 and 3, the travel of which inside the lower plate 14 is determined by various tensioning devices or other transmission pinions.
  • the profile of the endless chain 21 is similar to the external contour of the three arms 18, 19 and 20 forming the lower plate 14.
  • the above-described means ensuring that the various panels 4, 5 and 6 are driven in rotation and synchronized may be achieved differently, for example by the endless chain 21 being driven in rotation by a single component, namely a geared unit or a twin-action hydraulic actuator acting on the chain.
  • a hydraulic actuator permits various speeds of rotation of the panels, including a slow speed for the end of the first-side/second-side inversion course of the same panels.
  • each panel at its lower part comprises on the one hand a male coupling member 25 having two opposite joining heads 25a and 25b, and on the other hand a female joining member 26.
  • a male coupling member 25 having two opposite joining heads 25a and 25b
  • a female joining member 26 on the other hand.
  • each head 25a consists of a flat rod provided at its free end with a slot 25c
  • each female member 26 consists of two wings 68 and 69, integral with the lower part of a panel 4, comprising two respective coinciding slots 68a and 69a, and in the gap between which the flat rod 25a is inserted; in the insertion position, the slots 68a, 25c and 69a coincide.
  • the locking mechanism 27 comprises a lever 70, mounted in a rotational manner at one end on a fixed part 71, and comprising at its other free end a stud 72 penetrating in the locked position into the alignment of the slots 68a, 25c and 29a.
  • This stud is controlled in the disengaged position by activation of the electromagnet 73 acting on the lever 70, counter to the return means 74, or spring.
  • the return means 74 moves the stud 72 into the alignment of the slots 68a, 25c and 29a, so as to result in the desired locking.
  • the upper plate 15 is swivelled on the upper part 1b of the mast 1, by mounting in rotation of the hub 17 on the part 1b by means of axial guiding bearings 75 and a bearing 76 arranged on a shoulder of the part 1b and supporting the weight of the revolving support 2.
  • the rotation of the latter is provided by a motor (not shown) mounted on the top of the plate 15 and driving in rotation a shaft 77 which is swivel-mounted on the plate 15 and integral with a lower pinion 78, which meshes with an annular gear 79 fixed on the abovementioned shoulder of the stand 1b and on which gear the plate 15 finally rests via the bearing 76.
  • the display device comprises a means for blocking the revolving support 2 in rotation with respect to the stand 1, this means proving to be particularly useful as described hereinafter for blocking the rotation of said support when the wind speed reaches a certain threshold.
  • This blocking means comprises:
  • a blocking ring 51 fixed flat on the shoulder separating the lower part 1a and the upper part 1b of the stand 1, this ring comprising holes 51a distributed uniformly over its perimeter,
  • a control or monitoring device 82 mounted at the top end of the guide tube 81 and consisting of an electromagnet which controls a pin or key 52 opposite the ring 51; this key is controlled by the electromagnet 82, in parallel with the axis 3 of the stand 1, between two positions, namely a top position in which the pin is disengaged from the blocking ring 51, and a bottom position in which, by simple gravity and guided by the tube 80, the pin is engaged in a hole 51a of the ring 51.
  • the display device is equipped with various monitoring or control components making it possible in particular:
  • a microprocessor having a control or monitoring program makes it possible for the various functions shown by the flow diagram shown in FIG. 8 to be carried out.
  • the rotation of the revolving support 2 and the blocking of the latter in rotation with respect to the stand 1 can be achieved, not with separate means as described with respect to FIGS. 6 and 7 respectively, but with a single means.
  • the latter consists of a direct chain drive, with a wheel mounted coaxially on the revolving support and a pinion mounted on the mast or mount of the device; the pinion is driven in rotation by a geared unit having an electromagnetic brake which is actuated in the absence of current and provides both the driving and blocking in rotation of the pinion, and therefore of the revolving support.
  • the device for driving each panel individually in rotation may be replaced by a direct drive, without a frictional security mechanism 22, consisting in moving the endless chain 21 by a single drive means which is unique and common for the three panels; see FIG. 4.
  • the device for the mutual coupling of the panels described with reference to FIG. 5 can be omitted.
